Thank you so much. Lesson learned. I know taste my base and it definitely has spared me more mishaps. I wanted to know if there is a way to reprocess and save the work that went into it. I'm also doing what I should have done before: I'm researching. Thanks again!Passion fruit is very sour. You should cut the passion fruit juice with another type of juice, or try adding a bit more sugar if it won't affect texture too much.
You should definitely get in the habit of tasting your food before. Tasting the base will give you a good and better understanding of what you might need to do to correct the balance of flavors before spinning. Remember too that the flavors of your base should be just a little bit too strong (too sweet, too sour, etc) because the temperature of the sorbet (once frozen) will dull your palate.
